Natural science can be divided into two main branches: life science and physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, earth science, and astronomy. These branches of natural science may be further divided into more specialized branches (also known as fields).
Genetics – Science of genes, heredity, and variation in living organisms; Geochemistry – Science that applies chemistry to analyze geological systems – study of chemistry of the Earth's crust; Geochronology – Science of determining the age of rocks, sediments and fossils – study of measuring geological time
It's not rocket science, but a bit of good advice goes a long way. We asked bartenders to share tricks from the trade for making balanced and flavorful nonalcoholic drinks (mocktails, if you'd ...
